MRSA, an acronym for Methicillin-Resistant Staphylococcus aureus (or S. aureus), can be a bacteria which is known to trigger skin infections, in addition to other forms of infections as well. You can find various methods for patients to acquire these bacteria. It could be epidemic MRSA (EMRSA), it can be community-acquired (referred to as CA-MRSA or CMRSA), or it may be clinic or health-care-acquired (known as HA-MRSA or HMRSA). Some men and women who acquire these bacteria might only be carriers, meaning they do have the organisms in their bodies, but they may not be necessarily cause infection.
